This compound is sometimes represented as S2O4 for simplicity, but the correct stoichiometric representation is <strong>S4O2<\/strong>. It is a chemical compound where sulfur atoms are in oxidation states +2 and +4, and is known for its instability and strong oxidizing properties.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. <strong>Which of the following is associated with an acid?<\/strong><\/h3>\n\n\n\n<p><strong>Answer: D: all of the above<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>H3O+<\/strong>: This is the hydronium ion, which is present in all aqueous acids.<\/li>\n\n\n\n<li><strong>pH &lt; 7.0<\/strong>: Acids have a pH less than 7, with stronger acids having lower pH values.<\/li>\n\n\n\n<li><strong>Proton donor<\/strong>: According to the Br\u00f8nsted-Lowry definition, acids are proton donors.<br>Since all of these are characteristics of acids, the correct answer is <strong>D: all of the above<\/strong>.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. <strong>Given this system at equilibrium: N\u2082 + 3H\u2082 \u21cc 2NH\u2083.

In this case, if hydrogen (H\u2082) is added, the system will shift to the <strong>right<\/strong> to produce more ammonia (NH\u2083), in order to consume the added H\u2082 and restore equilibrium.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4. <strong>When a chlorine atom gains 1 electron, it forms an ion whose charge is:<\/strong><\/h3>\n\n\n\n<p><strong>Answer: A: -1<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Chlorine (Cl) is a halogen that readily gains one electron to achieve a stable octet, forming a <strong>Cl\u207b<\/strong> ion. The extra electron gives chlorine a <strong>-1<\/strong> charge.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">5. <strong>Which set of coefficients would balance this equation: Fe + O\u2082 \u2192 Fe\u2082O\u2083?<\/strong><\/h3>\n\n\n\n<p><strong>Answer: D: 2, 3, 1<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>To balance this reaction, you need to make sure the number of atoms on both sides is the same.\n<ul class=\"wp-block-list\">\n<li>On the left, you have Fe and O\u2082.<\/li>\n\n\n\n<li>On the right, you have Fe\u2082O\u2083, which means 2 iron atoms and 3 oxygen atoms are needed to balance the equation.<\/li>\n\n\n\n<li>The balanced equation is:<br><strong>2Fe + 3O\u2082 \u2192 Fe\u2082O\u2083<\/strong><br>Hence, the correct set of coefficients is <strong>D: 2, 3, 1<\/strong>.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner9-287.jpeg\" alt=\"\" class=\"wp-image-259006\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>What is the formula for disulfur tetraoxide?
